Mathematics Section

Kid's Place ~ Pick Your Grade  Welcome to our Mathematics Section. Math Expressions is a new math curriculum by Houghton Mifflin Harcourt. It offers new ways to teach and learn mathematics. Math Expressions uses objects, drawings, conceptual language, and real-world situations to help students build mathematical ideas that make sense to them.

Students represent 3-digit numbers with drawings that show hundreds, tens, and ones. To start, students make drawings on the dot arrays on their MathBoards. They show ones by circling individual dots, tens by drawing lines through groups of ten dots, and hundreds by drawing squares around groups of 100 dots. Math Expressions uses the terms ones, ten-sticks, and hundred-boxes to describe the three representations.
